Re: Electrical Check on your GTS

OK, I will be talking to my mechanic on this, to get it reinstalled.

However since we are talking about the cooling systems......



Here is my newly installed power steering reservoir (dry sump)



My new self burping (highest point) coolant overflow reservoir. In an overheat condition, the stock one dumps all the overflow from the plastic container directly onto the belts thereby compounding the beauty of losing not only the coolant, but also the water pump and the power steering pump. The belts slip and destroy themseves instantly. This happened to me while turning a corner. Brilliant design!



Here is a view of the racing power steering pump. My other one was running extremely rough. At one time we thought it may have been contributing to the belt slippage problem, but hey how could we be sure; we kept fighting wet belts!

Also a new water pump. The one I took out was a complete piece of crap. Everyone with one of those should be removing it. It was "as cast" (low quality sand casting), with no passage way machining. the clearances were so big I could stick my finger between the impeller and the cast passages at any location (literally). The replacement is cast with the passages machined to a clearance tolerance (novel concept eh!) and has a squirrel cage type of impeller which actually pushes the water through. The original one used a sheetmetal formed and poorly designed impellar which undoubtedly cavitated at speeds. I confirmed a truly poor circulation through various rev ranges, which is easily done by looking into the new aluminum overflow canister as it is plumbed that way from the thermostat housing, also seen here. (I also removed that and put in a restrictor plate, eliminating that variable) The new pump has a confirmed active water pressure. I tested it before and after waterpump installation.

Next to install is an all aluminium radiator and a higher pressure cap which completes the system redesign. The radiator gets replaced because of the suggestion that if the plastic sides blow, it will immediately cost the price of a new engine.

So bottom line is there are several parts to this equation that need to be adressed to make it right. I learned this the hard way-through some spoiled track days. Hopefully this will help some of you guys out.
